The sunset time is influenced by several factors, including the geographical location, time of year, and the position of the Earth in its orbit around the Sun. While it is generally true that locations farther north experience later sunsets during the summer months, there are specific instances when this may not be the case.
On March 6th, the sunset time in Seattle is later than in Los Angeles, even though Seattle is farther north. This can be attributed to the fact that Seattle is in the Pacific Time Zone, while Los Angeles is in the Pacific Standard Time Zone. In the United States, daylight saving time is observed in many regions, during which the clocks are adjusted forward by one hour in order to extend the daylight hours in the evenings.
Typically, daylight saving time begins on the second Sunday in March. However, the specific start and end dates may vary from year to year. Therefore, if daylight saving time has already begun in Los Angeles on March 6th, the clocks would have been adjusted forward by one hour, resulting in a later sunset time compared to Seattle, which may not have transitioned to daylight saving time yet.
It's important to note that this explanation is based on the assumption that daylight saving time is observed in both cities, and the specific details for a given year may vary. It's always a good idea to verify the current local time and any daylight saving time adjustments for the particular year and location in question.
